The Ecocirc electrically commuted spherical motor design offers many benefits over other pump styles. The Laing design operates on extremely low power input at a specified nominal voltage from 8 to 24 volts; the spherical permanent magnet eliminates impeller slippage which makes the Laing pump up to 40% more efficient than a standard induction motor. The motor has no shaft and therefore no shaft seal that is a wear point and potential leak path. Pump operation is virtually silent, with a low 35 db noise level. The brushless motor has a lifetime in excess of 50,000 hours when operated at nominal voltage and can be powered directly by solar panels, battery or other DC power sources. The unique screw ring design for this series of pumps allows for changing motors without disturbing the pump housing piping. The vario also features a potentiometer which allows the user to dial in the speed they need for the application.
The Principle of the Spherical Motor
Invented by Laing, it is fundamentally different from conventional canned motor pumps. The only moving part in a spherical motor is a hemispherical rotor/impeller unit which sits on an ultra-hard, wear-resistant ceramic ball. There are no conventional shaft bearings or seals. This eliminates bearing noise and seal leaks. This pump is robust and has an estimated service life in excess of 50,000 hours. The D5 Solar can be easily and safely installed by following detailed instructions from a Laing Installation Guide.
